Exam AWS Certified Advanced Networking - Specialty ANS-C01 topic 1 question 137 discussion

I go with B, Option A suggests ordering four 10 Gbps Direct Connect connections, which may be unnecessary for achieving the required 4 Gbps transfer speeds and could increase costs without providing significant benefits.

A is the right ans

So, Answer - A -- because they checking your english again not a engineering skills. 'B' - is OPTIMIZED option. 'A' is MAXIMIZED. Question is about MXIMAZIED solution -'A network engineer must design a highly available solution that **maximizes** resiliency.

The correct solution is A. Order four 10 Gbps AWS Direct Connect connections that are evenly spread over two locations. Terminate one connection from each Direct Connect location to a router at the company location. Terminate the other connection from each Direct Connect location to a different router at the company location. This solution meets the requirements because it provides the necessary 4 Gbps transfer speed and maximizes resiliency. By spreading the Direct Connect connections over two locations and terminating them at different routers, the solution can withstand the loss of circuits or routers, ensuring high availability. Please note that the other options do not fully meet the requirements. Options B, C, and D do not provide the necessary redundancy and resiliency. Option C does not provide the required 4 Gbps transfer speed.

To achieve 4 Gbps transfer speeds with high availability and resiliency, you would typically want to aggregate multiple AWS Direct Connect connections. Option A and Option B both involve ordering multiple 10 Gbps AWS Direct Connect connections, making them potential solutions. However, Option A provides additional redundancy by terminating connections to different routers at the company location, which enhances resiliency.

I think that it's correct answer is A.

A is an overkill but the question focuses on RESILIENCY. So A is the correct answer

If English is not your first language and you answer "B", then frankly, you are stupid.

maximum resiliency architecture

A network engineer MUST design a highly available solution that MAXIMIZES RESILIENCY

I think the right answer is B.

B provides high-availability and enough capacity during peaks.

Everyone voted for answer A but the answer does not even make sense. 1) Order *four* 10 Gbps AWS Direct Connect connections that are evenly spread over two locations. 2)Terminate *one connection* (not connections) from each Direct Connect location to a router at the company location. 3) Terminate the *other connection* (didn't say connections) from each Direct Connect location to a different router at the company location. What happened to the other two Direct Connect lines that was ordered? And there's no mention of LAG either. All the best.

My guess is that the answer lies in the following statement in the question "that maximizes resiliency" ie Maximum Resiliency DX Connection Design

A - doesn't say needs to be cost effective

A - The required speed is 4Gbps per location
